Patented Aug. 4, 1931 v PATENT OFFICE DAVID GUSTAVESON, OF LOS ANGELES,CALIFORNIA ROLLER MASSAGE MACHINE Application filed March 14, 1929.Serial No. 346,851.

My invention relates to a roller massage machine'that is especiallydesigned for eifecting a reduction of weight as a result of breakingdown and eliminating adipose tissue, and

the principle object of my invention is to providea relatively simple,practical and inexpensive machine wherein an applicator in the form of aroller, or a series of associated rollers is reciprocated, so as toproduce the rolling action against the body of the user. j

Further objects of my invention are to adjustably mount the machine on avertical support or supports so that said machine may be elevated orlowered for engagement with different portions of the body, further, toprovide simple and efficient means including an electric motor fordriving the reciprocating applicator and further to provide simple andefficient means for regulating and controlling the speed of thereciprocating applicator.

, Further objects of my invention are to provide an applicator that ismade up of a series of discs or rollers and further to provide meanswhereby the applicator may be mounted on a yielding support so that saidapplicator while in operation may change its position to conform to thecurvature of the body or limb to which-it is applied.

With the foregoing and other objects in view, my' invention consists incertain novel features of construction and arrangement of parts thatwill hereinafter be more fully described and claimed and illustrated inthe accompanying drawings, in which:

Fig. l is a front elevational view of a roller massage machine embodyingthe principles of my invention. Fig. 2 is a horizontal section taken onthe line 2 2 of Fig. 1.

Fig. 3 is an enlarged vertical section taken on the line 3-3 of Fig. 1.

Fig.4 is a top plan view of one of the applicators used in my improvedmassage machine. r

Fig. 5 is a side elevational view of the machine with parts thereof invertical section.

Fig. 6 is a vertical section taken on the line 6+6 of Fig. 5.

Referring by numerals to the accompany ing drawings which illustrate apractical embodiment of my invention 10, 10 designates a pair of uprightsupporting rails which may be secured to a wall or other verticalsupport and arranged for sliding movement upon said upright rails arehorizontally disposed brackets 11 to the outer ends of which areconnected the upper and lower portions of a vertically disposed boxlikehousing 12.

The front plate 13 of this housing is read ily removable in order togive access to the interior of the housing and formed in said frontplate is a vertically disposed slot 14:.

The rear ends of the brackets 11 or those portions that are mounted forsliding movement upon the uprights 10 are provided with suitable meansfor firmly securing the brackets to the uprights at differently adjustedelevations and these locking or clamping devices may be in the form ofset screws provided on their outer ends with small hand wheels or discs15.

Projecting rearwardly from the intermediate portion of the housing 12 isa horizontally disposed bracket 16, and extending lengthwisetherethrough is a pair of parallel rods 17 and mounted for slidingmovement upon said rods is a plate 18 upon which is mounted a smallelectric motor 19. The outer portion of one of the rods 17 isscrew-threaded for engagement with a threaded lug that forms a part ofthe base plate 18 and mounted on the outer end of this threaded rod is ahand wheel 20.

The parts just described provide simple means for moving the electricmotor carrying plate 18 longitudinally of the supporting rods 17.Depending from the plate 18 is a hook 21 and attached thereto is theouter end of a retractile spring 22, the inner end of ings 27 that areformed in the front and rear wall of gear case 28 and which latte-r 1sformed integral with and projects outwardly rom the left hand side wallof housing 12. V l/Vithin this gear case, shaft 26 is provided with aworm 29 that engages a worm wheel 30 and the latter being secured on theouter 7 end of a shaft 31 that is j ournaled in a hearing 32. Shaft 31projects into the upper portion of the housing 12 and carries a groovedpulley 33.

J ournaled in a bearing 34 in the lower portion of thelefthand side wallof the housing 12-is a shaft 35, the inner end of which carries agrooved pulley 36 that has the same meter as pulley 33 and mounted foroperation upon the pulleys 33 and 36 is a belt 37.

1 Arranged in the right hand'portion of the chamber within housing 12and directly to the rear of the slot 14 in the front wall is a air of uri 'ht uide-rods 38.'tl1e ends of p 7 D ID 1 which are fixed in the topand bottomplates of thehousln-g and arranged to slide freely upon theseguide rods 1s a. block 39 having a i bracket 40 that projects forwardlythrough massage machine may take various forms, but I prefer to usesectional rollers aslllustrated in Figs. 1, 2 and 4. V

In the form of applicator illustrated in Fig.

' 4 a horizontally disposed U-shaped frame 46 is provided with acentrally arrangedstud 47 that is adapted to be positioned in the recess41 in bracket 40 and to be clamped to said bracket by screw 42 andseated in the outer ends of the arms of said bracket46 are the ends of arod 48. Loosely mounted on said rod between the arms of the bracket arediscs or rollers 49 of uniform diameter with rounded perlpheries andsaid rollers being -52 in the bracket 40 and secured on the outer endconstructed of hard rubber, composition or the like. These rollers aremaintalned in spaced relat on by-relat1vely small thin washers 50. r

' This particular form of applicator may be conveniently employed whileimparting rotary massageto the back, breast or abdomen of the user, butwhere it isdesired to impart- .rotary massage to the lower port1ons ofthe le s or to the neck and chin I prefer to use an applicator of theform shown in Figs. 1 and 2. j

. This form-of applicator includes a horizontally disposed U shapedframe 51 thatis mounted for sliding movement upon a'stud which latter isadapted tobe clamped of the stud 52 in front of the rear bar of theframe 51 is a bow spring 53, the ends veniently used on the limbs orneck for im-' parting rolling massage thereto.

In the practical use of my improved roller massage machine the housingandparts car ried thereby is adjusted to the desired vertical height onthe supply supports 10 and the machine is clamped in its adjustedposition by tightening the clamping screws 15, and following the turningon of the current to the electric motor the latter will be operated inthe usual manner. V I r I Friction disc 24 engaging the, face of disc-25 will rotate the latter and the shaft 26 which lattervcarries worm 29and said worm drives worm wheel 30 carried by shaft 31 and which lattercarries the pulley 33. As pulley 33 is thus rotated the belt 37 will bedriven over the pulleys 33 and 36 and the pin 45 which enters slidingblock 44. will in its vertical travel reciprocate the block 39 upontheguide rods 38. V r V During the vertical reciprocation of block 39 orat the ends of its travel the pin 45 in passing from one side of thepulleys to the other will move the cylindrical block 44 horizontallythrough its housing or bearing 43. V The reciprocating block 39 carriesan applicator and as the latter is reciprocated vertically it willengage and impart rolling massage to that portion of the body thatispositioned immediately in front of the machine. By rotation ofthescrew rod that carries. the

handle 20 the base 18 thatcarries the motor may be moved laterallyrelative to-the housing and as this adjustment takes place the frictiondisc 24 willbe moved toward or away from-the center of the friction disc25Qwith the result that speed at which the machine operates may bereadily controlled'and regulated. T j

; Thus it will be seen that I have provided a roller massage machinethat is relatively simple in construction, inexpensive of'manufacture,capable of being readily. adjusted to diderent elevations and capable ofbeing operated at different speeds and which machine may be veryefl'ectivelyused forimparting rolling massage to practically allportionsof the body and limbs of the user.

It will be understood that minor changes in the size, form and,construction of the various parts of my improved roller massage machinemay be made and substituted for those herein shown and described withoutdeparting from the spirit of my invention, the scope of which is setforth in the appended claims.
